Mr Newby, 40, said:"I've never seen a bigger dog than Tiny. He's got 40in legs. I'm a 32in leg. He's bigger than some horses in the fields we walk past. It's funny when we are out walking and someone turns round – and almost jumps out of their skin. I get some funny looks when I'm calling him back to me, people look as if to say, "Tiny"? We used to have a dining room but now we have a Tiny room. He sleeps on a sofa."
